i Application filed March 9, 1917.' Serial No. 153,737.

To all whom t may concern:

Be it known that I, HARRY VISSERING, a citizen of the United States, and a resident of Chicago, in the county of-Cook and State ofvIllinois, have invented certain new and useful Improvements in Triple Sanding Ap-Y paratus, of which the" following is a specication.

My present inventionrelates to sand-ej ecting apparatus,l more particularly to .the track-sanding apparatus .commonly 'used for applying sand adjacent the points of contact of the locomotive wheels with the rails, and

has special reference to the provision of an improved structure adapted to apply sand to aplurality of pairs of wheels of the locomotive. The principal objects of my present invention are the provision of improved means of applying sand to a plurality of pairs olf,l

wheels;the4 provision of means for supplying substantially equalamounts of sand to each of a plurality of pairs of wheels; the

provision of means for supplying a plurality of front Sanders from a plurality of d'iiferent parts of av sand receptacle,the provlsion of means for supplying front. and rear Sanders from .the same part of a sand receptacle; the provision of improved means for applying sand to the locomotive wheels, either by hand or by Huid pressure; the provlsion of improved means for applying sand in front of and in rear of a locomotive Wheel; the provision of improved means for controlling` the amount of sand applied` to the Wheels; the provision of an improved form vof controlling valve for operating the.

' sanding apparatus, and generally, to im- Figure '1 is a diagrammatic side elevation,"

Auge, 191s. 4 Ais a eenen on the 1in@ 4 4 or4 The sanding apparatus is designed i' for i both Huid pressureand manual operation, so that while the apparatus Ais lnormally operated by fluid pressure it may-.still be operated when the source of'jliuid pressure fails. The luidmp'ressure operatingmeans will be described first.

`Referring'to Fig. 1, which illustrates theV general arrangernentA of the sanding apparatus, 1 represents the sandbox, 2 represents the sand -trapv operated. by fluid pressure,

usually compressed air, and 3, 4 and 5 the v pipes leading `to the wheels through whichl the sand issupplied tothe wheels..

The sand trap 2 isattached to the projecty ing base 64 of a; distributer bracket 6 5 I through which sand 'passes-.from Athe sand box to the trap and thence tothe p1pes 3, 4and-5."

. Inthe locomotive as shown, for purposesV of illustration, there are five pairsofdriv- -i to. the engine connecting rod and conseing wheels coupled together, namely, 6, 7,8, 9 and 10 the middle wheel S-being connected quently driven directly by the engine. Sand is desirably supplied to both wheels 6 and 8 for the reason that' if the -drivebe through thevwheels 8 and sand were supplied to the wheels 6 only, the other wheels, particularly wheel 8 being driven directly by the engine,

not having material resistance yto rotation when the Itrack is slippery, would tendto turn at greater speed than the wheel 6 which vis driven only by the connecting rods between the Wheelswith the result that the latter connecting rod -would ,become broken or Sandl is preferably applied 'to' the `front wheel in order to get the'maXimum-tractive effort but at the same time sand should `be applied to the wheel driven ldirectly 'by the engine. Y

@ne of the diiculties of track-sanding apparatus l have found is that it is diiicult to supply sand in substantially equal amounts to both wheels 6 and 8. This difficulty is, however, overcome by means of the apparatus which will now describe.

Sand from the sand box can pass through the distributer bracket through four passages 66, 67,68, and 69, of which passages 67 and 68 are normally closed by the manually operated valves 62 and 63. The several passages 66, 67, 68 and 69 register with the passages 20, 70, 71 and 21 in the sand trap. The angle of slope of the passages 67 and 68 (with their continuations and 71) is greater than the angle of repose of sand so that sand will ow through them when not otherwise prevented. It will be seen by inspecting Figs. 2, 4 and 8 that if either of the valves 62 or 63 are` lifted there will be a clear uninterrupted passage for sand to the pipes 3 or 4. On the other hand, although sand is free at all times to enter the passages 66 and 69 and their continuations 20 and 21, gravity/ How of sand is prevented by the fact that the sand must pass through the upturned tubular parts 22 and 23 before reaching lthe passages leading to theV sander pipes. These tubular parts 22 and 23 form part of the fluid ejecting means, illustrated more i particularly in Figs. 2 to 5. i

Inlet pipes 11, 12 and 13 `are provided through which Huid under pressure, preferably compressed air, is passed to blow sand through the pipes 3, 4 and 5 respectively.'

The sand passes out of the trap by means of the threaded connections 1 4, 15 and 16 which are connected, respectively to the pipes 3, 4

and 5.

Referring now to Fig. 1, it will be seen that. there are. two' compressed air pipes 17 and 11. 'llhe pipe 17 is connected to the' branch pipes 12 and 13. When compressed air is passed through the pipe 17 sand `is ejected through both pipes 4 and 5, and when compressed air is passed through the pipe 11 sand is ejected through the pipe 3 only. The linterior construction of the sand trap 1s shown more particularly in Figs. 4 and 5. Considering first the means for supplying sand to the pipes 4 and 5, it will be seen on reference to Fig. 4,'that two sand ejecting devices are provided having jets 18 and 19 respectively, through which compressed air is blown in ord'er to draw sand throughy the orifices 20 and 21, respectively, from the` sand box 1. The sand is blown through the tubular parts 22y and 23 of the trap body which may be provided with lead llinings 24 and 25 which will stand the abrasive action of the moving sand more successfully than steel or the other material of the trap body. The sand then strikes plugs 26 and 27, provided with lead inserts 28 and 29 whose function is the same Aas that of the sleeves 24 and 25. rll`he sand is then' carried by the air `to the threaded connections 15 'and 16, and from thence to the4 pipes 4 and 5. Plugs 30, 31, 32, etc., are provided for facilitating the cleaning of the trap from sand and other material which may have become lodged in the passages through which the compressed air is passed.

The construction of the means for supplying sand to the rear of the wheels by the pipe 3 is shown in Fig. 5, and as its construction is similar to that shown iny Fig. 4 for the other pipes, there is no need to describe this construction further.

sages leading to the front and rear sanders 3 and 4 the admittance of fluid under pressure into either pipe 11 or 12 produces` a How of sand toward one sander only. This is due to the fact that the compressed air or the like is introduced under pressure th cough a fine orifice and consequently at a considerable velocityI which issufiicient to prevent the air exhausting through the wrong passage either entirely or at least sufiicientlyrapidly to draw sand with it. 0n the other hand sand for the two front Sanders is takeni from the different parts of the sand receptacle so that the ile of sand in the latter is reduced fairly uni orrnly as the rear sander is rarely used as compared with the front Sanders. On account of therarity with which the rear Sander is used and on account of the nor- `\mally much lower speed on reverse than on forward movement, only one rearI sander is used this being placed to operate on the y wheel directly coupled to the engine.

My improved sanding device is applica- '36, and also by reason of the fact that the high-pressure side of the valve is on the same side of the valve as the spring 36 so that the valve is pressed against its seatby luid presusre as well as by spring pressure. A suitable connection 37 to a source of fluid pressure is provided and a suitable closing member 38 is arranged to screv into the body 33 of the valve and hold the springr 36 freas'on of the engagement of this rounded en'd with one of the yrO'undedr'eCeSSesl 43 in the body ofthe valve 33, the valve handle' can be readily moved by hand int-ol any de-v sired position. The handle 37 -is mounted 'i with their corresponding' port in the body.

-thus avoiding depl on a squared end 44 on the shank 45 yof the valve 35. A bolt 46 and a Washer 47 are. provided for holding the handlev 37 in posiv tion on this squared, portion 44.

In order to adjust the amount of sand delivered by the sanding apparatus .provision ismade for supplying varying amounts of compressed air, and for this purpose I have provided in the valve 35 three ports of graduated sizes-48, 49 and 50 for. the rear sander, and three -graduated ports 51,52 and 53 for the `front sander. The ports v1n. the

valve'- body 3 3 are arranged so as to uncover .first one and then the other of these` ports so that the amount of air can be'pro# 'st an'tially larger, preferably twice as large as the one rear sanderfwhile there are twozfront Sanders.

The rounded recesses 43 are arranged so that as the latch is moved into successive refl cesses the nports 48,l 49 and 50 on-the one hand and the ports 51, 52 and 53 onthe.

other are successively brought Iinto register of the valve.

An alarm device50 is providedfor indicating when the sander is in operation and passed.

For thispurpose two rods 54, 55 are arranged to lead to facilitatetheir manipulation. 4The levers 56 and 57v are arranged to liftthe rods 60v and 61 'respectively 'to which are' connected the `valve members 62 and 63 (see Fig. 8).A If the valve 62 be lifted',I sand flows by gravity through thepassages 67 andZ'O leading a tothe rear sanderpipeB.
